The following is something which I would really like to see corrected
as soon as possible. I can't say how difficult it is to fix, but it
is essential to piano music. Unfortunately, it is virtually
impossible to apply workarounds for the start and end problem of ties
-- if there is one please tell me.

% . For chords in tight context, ties must occupy horizontal space for
% themselves. I consider this as a severe problem.
%
% . The start and end points of ties are not correct in chords with
% seconds. This is also a severe problem IMHO.
%
% . The curvature of small ties is too big.
%
% . The algorithm to choose the direction of the ties doesn't work
% properly. I suggest the following for applying ties sequentially
% from top to bottom:
%
% + The topmost tie is always `up'.
%
% + If there is a vertical gap to the last note above larger than
% or equal to a fifth (or sixth?), the tie is `up', otherwise it
% is `down'.
%
% + The bottommost tie is always `down'.
